NEW YORK--U.S. stock futures waffled around unchanged levels, with investors looking ahead to reports on jobless claims, personal income and spending to see whether the market can end the strongest January in decades on a bright note.

About 90 minutes ahead of the open, Dow Jones Industrial Average futures inched lower by one point, or less than 0.1%, to 13837. On Wednesday, the Dow fell 44 points, or 0.3%, the biggest one-day decline since Jan. 8, but was still on track for its best January performance since 1989.

Data on initial claims for jobless benefits in the latest week are due out at 8:30 a.m. EST. The median estimate of economists surveyed by Dow Jones Newswires is for a rise to 365,000 from the previous week's 330,000.

Also at 8:30 a.m. EST, personal income for December is seen rising 1% on the month, consumer spending is expected to rise 0.2% and core personal consumption expenditures are pegged to rise 0.1%. At 9:45 a.m., the Chicago-area purchasing managers index for January is expected to rise to 50.0 from December's 48.9; a reading of 50 and above indicates expansion.

Among stocks seeing premarket activity, shares of Facebook slid 6.7% after the social-network company reported fourth-quarter earnings and revenue that topped analyst estimates, but its operating margin narrowed and costs surged on the year, and monthly active visitors rose modestly from the third quarter.

European markets were broadly lower, with the Stoxx Europe 600 off 0.4% and on track for a two-week closing low, following weak German data and after the U.S. Federal Reserve late Wednesday said economic activity paused in recent months.

Retail sales in Germany fell 1.7% in December, much worse than expectations of 0.2% growth. Germany's DAX index lost 0.3%.

Asian markets were mixed, with Japanese stocks finishing off a strong month on a bright note amid broad gains in the banking sector. Japan's Nikkei Stock Average rose 0.2% on the day, and climbed 7.2% on the month, to the highest level since October 2008. China's Shanghai Composite gained 0.1% to an eight-month high, while Australia's S&P ASX 200 declined 0.4% to snap a 10-session winning streak.
